Telematics SIM Card

[davewill]

Taking out the SIM card is not really a solution...

It's a puzzler that I wish I could solve.

Take out the sim. You will either solve the problem for everyone by figuring out how the easily accessible numbers should be used, find out it can't work, or at least solve it for yourself.

I thought I already solved this problem. There is no phone number associated with the sim. The company that issues the sim is very integrated with the GSM network and the system doesn't work the way we expect it to because it doesn't have to.

As I already posted in the third post 882-35 is the international network number for Jasper Systems, inc, which happens to partner with AT&T and (assumingly) is the company providing the network access.

It does sound like the number is the MSISDN, which probably means there isn't "phone number" attached to it as they access it directly by the MSISDN at the BSC/MSC level...something our mobile phones are not expecting (they expect a phone number).

All SIMs have an associated MSISDN, even if its a fake one, for billing purposes. The +88235...etc is the actual associated MSISDN.

The microcell specifically needs AT&T MSISDN's programmed in. The CCDID is nothing more than a serial number that directly relates to the real (purportedly secret) identity of the SIM: the IMSI. Microcells are a consumer device, and were never really intended to communicate with random M2M modules that will probably be more common place. Maybe that will change...for that carrier's M2M devices at least!

Yes, Jasper uses AT&T, but its sort of an MVNO roaming agreement.

Its really too bad the car does not have WiFi, as I have been in locations where I had problems with charge timers, and the iPhone app would have corrected the problem. Oh well.

Because I hate to give up without exhausting all possibilities, I'll try the SIM card play. Has anyone published a step-by-step for removing the Telemetrics unit? I see images of it in this thread, and I see the glovebox removed.

Any guidance?

Follow the service manual instructions. It was pretty easy when it shows you where all the clips are and what direction they pull out.

Just make sure you remove ALL the screws before yanking on it hard. There are some that aren't too easy to see.

CARWINGS will tell you everything you need to know about the SIM provisioning if you visit the ID "feed", including MSISDN (phone number).

[turbo2ltr]

What is the ID "feed"?

What is the ID "feed"?

Go to CARWINGS and "All Feeds"...then find the ID feed.

My ID feed was completely empty. Zero content.

Okay, a little CARWINGS 101 for you noobs:

Feeds can contain more than just a picture and some audio, there is plenty of data....of course...you need to push some very counterintuitive controls that make no sense.

At a stop, hit pause.

Note the selections on the right that appear. Things that can live her are text-to-speech, further descriptions, commands to put a destination specified in the feed into the nav, etc.

Don't feel bad, I just figured this out last week
